What is Ansible Check?
A structural validator for Ansible playbooks: plays must be mappings with hosts (or import_playbook), and tasks ideally have names.
How it works
The YAML parses as a list; each play is checked for hosts/import_playbook and each task list for name warnings.

Examples
Playbook pre-flight
Validate an Ansible playbook for valid structure — hosts, tasks, and module keys — before running it against inventory.
Common mistakes
Not a full ansible-lint replacement
This checks structure and common errors locally; it can't validate against your roles or collections.
Frequently asked questions

Play and task structure, required keys like hosts and tasks, and YAML validity.
